-If you tell a big enough lie and tell it frequently enough, it will be believed.
-Make the lie big, make it simple, keep saying it, and eventually, they will believe it. (For years no I have said: "Tell people enough times..., with enough conviction..., and they will believe just about anything!")
-The great masses of the people will more easily fall victims to a big lie than to a small one.
-The victor will never be asked if he told the truth.
“All propaganda has to be popular and has to accommodate itself to the comprehension of the least intelligent of those whom it seeks to reach.” – Adolph Hitler
